USB dongle is not used, service doesn't restart

Hi,

I have the issue that my dongle is not used. It has been working, but then stopped for some reasons. Restarting, stopping service takes quit long. 

Also system hangs after sudo reboot. Don't know if virtualhere causing this issue too.

I would be grateful for any hints!
